Abstract
An approach is provided for interworking traffic onto a composite transport group (CTG). An attribute associated with a composite transport group is determined based on a characteristic of a traffic flow associated with a label-switched network. The traffic flow is mapped to one or more component connections of the composite transport group based on the attribute.
Claims20
A method comprising:
- determining an attribute associated with a composite transport group of a composite transport group domain, based on a characteristic of a traffic flow associated with a label-switched domain;
- mapping the traffic flow to one or more component connections of the composite transport group based on the attribute;
- assigning a bandwidth to the one or more component connections according to an automatic bandwidth configuration scheme, wherein the automatic bandwidth configuration scheme defines a first adjustment window for increasing the bandwidth and defines a second adjustment window for decreasing the bandwidth, each of the adjustment windows specifying one or more measurement intervals;
- determining, during the first adjustment window, to increase the bandwidth if a current bandwidth is greater than a sum of the bandwidth and a bandwidth burst threshold;
- and
- determining, after the first adjustment window, to increase the bandwidth if a maximum determined bandwidth is greater than a sum of the bandwidth and a bandwidth adjustment threshold,
- wherein the one or more component connections host at least a portion of the traffic flow associated with the label-switched domain.
